What were the significant goals of US foreign policy from 1946 to 1965?

The most significant goal of American foreign policy
throught this entire time period was the goal of containing communism.  This goal led to
the most important actions that the US took in foreign policy during this
time.

Almost immediately after the end of WWII, the US
started trying to prevent the spread of communism.  This was the main goal of US foreign
policy at least through 1965.  It led to such US actions as the
following:

• The Marshall
  Plan


• The Truman
  Doctrine


• The Berlin
  Airlift


• The Korean War


• The
  overthrows of Mohammed Mossadegh in Iran and Jacobo Arbenz in
  Guatemala.


• The Bay of Pigs
  Invasion


• The Cuban Missile
  Crisis


• The Gulf of Tonkin
  Resolution

These constitute the most important
actions that the US took in foreign policy during this time period.  Each one was
motivated by the desire to contain communism.
